SCREEN FASTENER Filed Nov. 7, 1945 Inventor Car/0 y WWW Patented May 23, 1950 SGREENJAflENEE :Glen 0..Garper, Charleston-aw. Va.v Application November 7, 1i ls1, 5;S,erial' 151 5211433 3 Claims. (!;3292-9-202) 'Ihe: present invention relates to a novel and improved screen fastener, particularly a type of fastener :which; lends itself; adaptable 'for proper application and use in association with asteel .sash window screen.

.gfIhe obvious and principal. purpose pfthe, in-

..rention isto provide a simple, ,practical.andconvenientjf astener which, in fact, is similanto, a. ,turnabutton and which issodesigned and mounted as tofunction correctly and adequately in relation to a removable-window screen such as is applicable to a now somewhat standardsteel :sash .window.

Briefly, the preferred embodiment of the invention comprises a bolt which is threaded into an existing or stock screw threaded opening in the steel sash window, said bolt serving as a pivot and also serving to accommodate the turnable latch or turn-button, the latter being provided with a convenient handle and being held in screen retaining position by a coiled spring coacting therewith and also with the shank of the bolt.

Other objects, features and advantages of the invention will become readily apparent from the following description and the accompanying illustrative drawings.

In the drawings:

Figure 1 is a View showing fragmentary portions of the sash frame and screen, the improved fastener being illustrated and in position for releasably holding the screen in useful position.

Figure 2 is a perspective view of the fastener per se with the bolt and spring omitted.

Figure 3 is an elevational view showing the complete steel sash, the screen superimposed against the exterior thereof, and illustrating a plurality of fasteners in actual use.

Referring now to the drawings by distinguishing reference numerals, it will be seen that the steel sash window or frame is denoted by the reference character A and the standard outside removable screen is indicated at B. I use a plurality of fasteners for holding the screen in place as shown in Figure 3, but will describe only one as they are all alike.

As before indicated, the fastener per se is in the form of a latch or turn-button 5 this being of general U-shaped form. The relatively long arm 6 is provided with a bolt hole I as seen in Figure 2. The free end thereof is tapered and fashioned as at 8 to provide the detent. Mounted integrally and inwardly of the detent is the cured rigidly tothe det nt and extending at right angles and providedwith a lateral flngergrip I I. The-handle is in the form of; aminiature crank. '--'Ihe sherter limb-or-arm lz {underlies the longer arm fi -a-nd is connected thereto; by aconnecting or bight portiem l3.- f-The-free=-terrn inalof the short "arr-n l2-is--provided with a notch I4 of semi-circular -=ferm ,-"this being in line with the bolt hole 1. The bolt'-eomprises -a; shank with a screw-threaded portion l 5 and a smooth pivot donning portion l6.- The; latter terminates -in a head 11 provided witha-screwdriver kerf l8. The smooth portion Off the shank goes through the bolt hole l and the threaded portion -coacts witheand passes through and" beyond the notch M where it is threaded into a screw-threaded hole I9 in the frame or steel window sash A.

The notched limb l2 rests firmly but in rotatable contact with the adjacent face of the steel sash A and the bight I3 is sufficient in length to permit the detent A to overlie and retain the frame of the screen B in proper position. The latch is assembled through the medium of the bolt and the bolt also serves as a pivot for said latch and a coil spring 20 surrounds the smooth shank portion of the bolt being located between the apertured limb 6 and the head H. The spring exerts just sufficient tension to hold the detent against the screen and the screen properly in place. Hence, when it is desired to release the screen the crank or handle is grasped and the latch or turn button is swung around the pivot I6 in an obvious manner to clear the detent from the marginal edge portion of the screen frame. The invention is quite simple and therefore the mode of application and operation is no doubt clear.

A careful consideration of the foregoing description in conjunction with the invention as illustrated in the drawings will enable the reader to obtain a clear understanding and impression of the alleged features of merit and novelty sufficient to clarify the construction of the invention as hereinafter claimed.

Minor changes in shape, size, materials and rearrangement of parts may be resorted to in actual practice so long as no departure is made from the invention as claimed.

I claim:

1. A latch-type fastener adapted to secure the frame of a creen or the like to a, relatively stationary steel sash frame comprising a one-piece U-shaped member, said member including a rectilinearly straight long limb provided interba-n 9. this p ising a lone shank l0 seit mediate its ends with a smooth-edged bolt hole,

the outer free end portion of said long limb being fashioned to provide a detent which is adapted to engage over the edge portion of a, screen frame, said member further including a short limb complemental to the long limb, said short limb underlying the long limb in parallelism, the free end thereof being provided with a bolt accommodation notch, said limbs being joined together at corresponding ends by a bight portion, and said short limb being of a, length in relation to the length of the long limb that the notch therein is in partial alignment with said bolt hole.

2. A latch-type fastener adapted to secure the frame of a screen or the like to a relatively stationary steel sash frame comprising a one-piece U-shaped member, said member including a rectilinearly straight long limb provided intermediate its ends with a smooth-'edgedbolt' hole,

the outer free end portion of said long limb being fashioned to provide a r detent which is adapted to engage over the edge portion of a screen frame, said member further including a short limb complemental to the long limb, said short limb underlying the long limb in parallelism, the free end thereof being provided with a bolt accommodation notch, said limbs being joined together at corresponding ends by a, bight portion, and said short limb being of a length in relation to the long limb that the notch therein is in partial alignment with said bolt hole, a bolt having a to. 1,912,850

shank with smooth and screw-threaded portions, said shank passing through the bolt hole and being partly seated in said notch and adapted to thread into a screw-threaded socket in a sash frame, the headed end of the shank being at a point outwardly of the long limb, and a coiled spring surrounding said shank between the head and said long limb.

3. A quick releasable screen fastener for a steel sash window comprising a headed bolt having a shank with a screw-threaded portion and a smooth portion, a U-shaped latch embodying a, long limb having a bolt hole through and beyond which the headed end of said shank extends, a short limb, and a connecting bight between corresponding ends of said limbs, said short limb being spaced in parallelism to the long limb and having a notch formed in its free end seating and partially embracing the bolt, the free end portion of said long limb being provided with a detent and an outstanding angularly disposed rigidly attached crank-handle.
